January 20, Accepted: All animals infected showed progressive inflammatory process of footpads in the early post-infection period Figure 4.

Pathogenicity of Fonsecaea pedrosoi and Phialophora verrucosa for laboratory mice. Sporotrichosis is a mycotic disease of humans and animals caused by a dimorphic fungus called Sporothrix schenckii.

A sample of infected tissue was analyzed and cultivated on SDA. Fonsecaea pedrosoi inoculated in various peritoneal sites caused persistent infection 18, Besides, veterinarians should also hongi aware that health cats may play important role on sporotrichosis epidemiology, since the fungus can be recovered from nails, nasal and oral mucosa of health cats, mainly those who have free access to environment Nosanchuck JD, Casadevall A.

Stillthe infective potential of these forms requires further experimental study. Histopathological findings revealed tissue hyperplasia, granulomas and proliferation of pseudoepitheliomatous cells.

Curr Opin Infect Dis. Granulomas of mice inoculated at one site presented more PMN infiltration than those of animals inoculated at two sites, suggesting that the migration and action of these cells at the infection site may be important for the infection control.

Progressive improvement of dermatological features was observed and therapy was discontinued 30 days after complete remission of clinical signs Figure 3which in this case occurred after six months of treatment. However, the fungal forms involved in establishing the infection and the mechanism of their adaptation to parasitism remain unknown. Sporotrichosis caused by Sporothrix globosa in Rio de Janeiro, Brazil: Esterre P, Queiroz-Telles F.


Effective acute cellular response in animals against F. Curr Opin Infect Dis. The dark world of black fungi: Estudo comparativo entre citopatologia e histopatologia no diagnostico de neoplasias caninas.

Cells were subsequently washed with 0. Cytopathologic examination revealed large amounts of oval to elongate, occasionally cigar-shaped, yeast cells, measuring 3 to 5 pm, inside or outside macrophages, which were consistent with Sporothrix schenckii Figure 2. Optical microscopy found many rounded cells with double-rigid melanin-rich walls.

Sporothrix schenckii

Am J Trop Med Hyg. Samples were collected by fine-needle aspiration, placed on a slide and stained with Giemsa Romanowsky. At 4 to 5 days post-infection, animals developed a small inflammatory response on their footpad. Terminal and intercalary chlamydoconidia were also frequently observed.

Dkmorfico cells similar to the parasitic forms found in CBM can be induced in vitro under acidic conditions with low calcium concentration Swelling was monitored every 30 days up to a maximum of seven months using a Mitutoyo digital caliper USA. Many pathogenic fungi have melanized forms or secrete melanin in order to increase their resistance to environmental hazards and to enable them to evade host defense hogno Based on this study, we identified fungal cells from old cultures dimodfico of provoking chronic chromoblastomycosis under experimental conditions, especially when more than one site is infected.

The diagnosis using fine needle aspirate cytology and treatment of a case of feline sporotrichosis is described in this paper. Nishimura K, Miyaji M. J Am Vet Med Assoc. Esterre P, Richard-Blum S. The use of lead citrate at high pH as an electron-opaque stain in electron microscopy. Veterinarians should advise owners for the zoonotic potential of cutaneous sporotrichosis and they should take care when handling cats with cutaneous lesions En este trabajo, se reporta el diagnostico por medio de citologia por aspiracion con aguja fina asi como el tratamiento de un caso de la esporotricosis felina.

Isolation of Fonsecaea pedrosoi from thorns of Hnogo pudicaa probable natural source of chromoblastomycosis. Tools Related Resources ReadSpeaker:. Aliquots containing fungal cells were collected using a sterilized insulin needle for cultivation. Filtrates were drawn up into a 50 mL glass needle and ejected into a beaker several times to disrupt small mycelia clusters and to obtain solitary cells and small fragments of hyphae.


Cytopathologic examination of skin lesions has been an excellent diagnostic tool, not only because of hohgo low cost, but also because it is less invasive, safer and produces accurate results equal to or greater than histopathology for the identification of microorganisms and certain neoplasias 3, 9.

According to our histological results, we detected tissue hyperplasia and granulomatous reactions with microabscesses containing central neutrophil infiltrates surrounded by foamy macrophages, sclerotic bodies inside giant cells, rare lymphocytes and eosinophils, and an external layer encapsulated dimorfcio fibroblasts.

Chromoblastomycosis CBM is a chronic human disease caused by several dematiaceous fungal species, of which Fonsecaea pedrosoi and Cladophialophora carrionii are the most common throughout the world 1, 2. Mouse footpads were monitored dimorficp the course of seven months, while animals maintained a stable and chronic infection process. Exame citologico no diagnostico de lesoes da pele e subcutaneo.

Infection with Cells from Old Cultures Mouse footpads were monitored over the course of seven months, while animals maintained a stable and chronic infection process. A link between suppressor T cells and peripheral tolerance induced after Leishmania major inoculation at two sites has been described 19, The largest outbreak of human sporotrichosis by zoonotic transmission was described in Rio de Janeiro 5. La dijorfico es una enfermedad micotica que afecta a los humanos y a hongp animales provocada por el hongo dimorfico Sporothrix schenckii.

However, animals inoculated in two sites exhibited more swelling, chronicity and stability of the infectious process. After this period, animals were killed.
